Driving a partially automated car with the hands on or off the steering wheel : users' subjective experiences
Résumé
Which are the subjective feelings and objective risks of driving in an
automatic mode when holding the steering wheel or not holding it? Two conditions of simulated driving of a partially automated car have been tested (handson and hands-off), in two situations of driving on highways including critical events forcing the driver to take over. The user subjective experiences were compared: the situation awareness, feelings of safety, control, attention, onboard activities, psychological and physical comfort were analyzed on the basis
of in-depth interviews right after the activity. For the critical situations designed, the performance results indicate a negative impact of the hands-off condition on the takeover. The hands-off condition is appreciated for its comfort
and the multi-activity it allows, but the hands-on condition is objectively and
subjectively safer in critical situations.
